This is a simple 1 LoopBox kit that allows you to DIY your own one effect loop. 1LoopBox is a versatile effect loop box. Use it as an effect loop to turn multiple effectors on and off, and even vintage effectors that can make a big difference when bypassing can be used as a true bypass pedal. You can also use it as an ABBox. When you step on the foot switch, the output can be switched between SEND and OUTPUT, so you can use it to switch tuner out or amplifier. It is also a convenient input selector when switching between multiple instruments. Mini size makes it easy to handle and does not take up much space inside the board. The power supply is only used to light up the LED, so if you dont use the LED, it will work without the power supply. Easy to create, perfect for first effectors. Soldering iron, screwdriver and nippers are required for production.
